A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

Just a somewhat chaotic list of personal Proxmox VE related tips/notes or interesting (to me) things I'm working on or experiment with.
Some of the things you see here are niche or purely experimental. I try to label them as such, but as always with random code snippets, make sure to review anything before running it in your own environment. Perhaps test in a virtual PVE first.

Please note that unless you see a shebang (#!/...) these code blocks are usually meant to be copy & pasted directly into the shell. Some of the steps will not work if you run part of them in a script and copy paste other ones as they rely on variables set before.
The { and } surrounding some scripts are meant to avoid cluttering your shell history with individual commands, etc. You can ignore them if you manually copy paste the individual commands.

This is to solve an issue where you use a non-apple european keyboard with the US keyboard layout in macOS where the Tilde key is in the wrong place.

This is the process for the Logitec MX Keys Mini

• Connect the keyboard (bluetooth)
• Make sure the keyboard is in PC mode (hold fn + p for 3 seconds)
• Go through the keyboard wizard and at the end select the European ISO... layout
• Switch the keyboard to Mac mode (hold fn + o for 3 seconds)
• Tilde should work

If this doesn't work:

A Claude Code Agent Skill built from Dex Horthy's (HumanLayer) playbook on David Ondrej's podcast.

"Once the model has written thousands of lines of code, it is harder to change. The sessions that generate design docs are context-light — you get the most model intelligence when you do the hard thinking early."

By default, agents build horizontally: all the backend, then all the frontend, then a 2,000-line diff lands in your lap and reviewing it is your problem. This skill flips that. Every decision that matters gets made before the code exists — where changing your mind costs a sentence, not a rewrite.

• Kernel -- software that manages the system by providing access to hardware and other resources (memory, network stack, scheduling cpu, etc). Runs in priveleged CPU mode -- kernel mode. It uses kernel-space stack.
• Process -- an OS abstraction for running programs. Runs in user mode with access to kernel mode via system calls. It consists of: memory address space, file descriptors, thread stacks, registers. Process uses user-space stacks. For example, syscalls use a s kernel exception stack associated with each thread.

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
